Injecting behaviour of injecting drug users at needle and syringe programmes and pharmacies in Australia

Objective: To compare demographic and injecting characteristics of clients collecting needle syringes from needle syringe programmes (NSPs) and pharmacies. Methods: Clients obtaining needle syringes from three NSPs and one pharmacy in the same geographic area during one and four weeks, respectively were asked to complete a self-administered questionnaire. Results: Approximately half the 336 NSP (56%) and 63 pharmacy (49%) respondents reported using both NSPs and pharmacies in the past month. NSP and pharmacy respondents were similar on many characteristics: male gender (60 and 62%, respectively); median age (30 years for both groups); median age at first injection (18 years both groups); history of methadone treatment (62 and 53%); and heroin as the last drug injected (60 and 59%). NSP respondents were more likely than pharmacy respondents to report imprisonment in the previous year (20% versus 8%, P=0.05), daily injection (67% versus 56%, P=0.09) and re-use of more than one other person’s needle syringe in the previous month (27% versus 7% of 52 and 15 reporting needle syringe re-use). Pharmacy respondents were more likely than NSP respondents to report amphetamine use (32% versus 10%, P<0.001), shared use of tourniquets (24% versus 12%, P=0.01), spoons (43% versus 32%, P=0.09), filters (22% versus 15%, P=0.1), or drug mix (16% versus 9%, P=0.1), and difficulty finding a vein (73% versus 26%, P<0.001). Conclusion: The risk profile of IDUs (Injecting Drug Users) recruited at various sites provides important information for behavioural surveillance and health promotion efforts. Increased convenience of needle syringe access enhances HIV prevention efforts, however, appropriate education is required for people obtaining needle syringes at pharmacies to reduce sharing of injecting equipment other than needle syringes.
